The studies at UMR8235 are performed in the context of physico-chemistry and interfacial reactivity. Various domains are concerned: corrosion and its inhibition, surface treatments, storage and conversion of energy, and, more recently, applications in biology, cultural patrimony protection, and, more generally, themes related to the behaviour of interfaces in natural environments. This explains why the laboratory is positioned at the junction of fundamental research, its primary assignment, and activities with partners of various economic sectors using electrochemical concepts, techniques, and processes.
The skills and fields of activity include:
- the development of methods dealing with concepts of electrochemical kinetics and design of sophisticated instrumentation able to apply these concepts to various physicochemical processes occurring at metal-electrolyte interfaces.
- the preparation or modification, structural and/or chemical characterization of electrochemical interfaces and systems, and modelling of their electrochemical behaviour. This activity may lead to the characterization of specific functionalities and to the development of innovative applications.
This duality was organized around two teams since 2003, but discussions inside the LISE Scientific Council in 2016-2017 led to a review of this organization to improve the internal functioning of the laboratory. As shown by the organization chart, the research was structured around 3 themes:
and 4 transverse axis:
|Axis 1. Electrochemical kinetics and modelling, impedance spectroscopy (leaders K. Ngo, L. Fillaud)|
|Axis 2. Instrumental developments and coupling of techniques (leaders K. Ngo, I. Lucas)|
|Axis 3. Electrochemical storage and energy conversion (leaders O. Sel, C. Sanchez-Sanchez, I. Lucas)|
|Axis 4. Thin films, surface treatment and corrosion (leaders J. Pulpytel, M. Tran, A. Pailleret)|
The mastery and development of original characterization methods remain a strong axis in the LISE research to study the kinetics of complex electrochemical phenomena. The expertise of LISE is recognized worldwide in the field of electrochemical impedance measurements, global and/or local, and the definition of multiple transfer functions (electrical, gravimetric, material flow...). Very recently, a major effort was made to set up a NanoRaman platform coupled with electrochemistry.
